Description

Technical Field

[0001] This invention belongs to the technical field of intelligent manufacturing and aquatic product processing equipment, and particularly relates to an automatic shelling and cleaning machine for crustaceans. Background Technology

[0002] my country's crustacean seafood industry has become an important part of the development of aquatic products, and there is an urgent need for supporting high-efficiency industrial processing equipment.

[0003] Currently, the processing of crustaceans, including shelling and cleaning, is still primarily done manually. The limited amount of related equipment is mostly single-function machines, failing to integrate shelling, evisceration, and cleaning. This manual processing method is limited by labor costs, operator skill levels, and labor intensity, making it difficult to guarantee processing efficiency and food safety.

[0004] In existing technologies, such as Chinese patent CN118765961A, a device for automatically separating the shell and meat of crustaceans is disclosed, which uses a top-removal mechanism for shell removal. However, a common drawback of this existing technology and similar products on the market is that it uses a static, rigid "shell-removing top knife" for shelling. When the conveyor belt pushes the crustaceans towards the static top knife, if there are slight differences in the size of the crustaceans, the rigidly fixed blade can easily crush the crustaceans directly, such as the carapace of crabs or even the crab meat, causing shell fragments to embed in the crab meat. This not only results in a low yield but also seriously affects food safety. In addition, due to the lack of smooth mechanical coordination between the shell-opening, shell-removing, and cleaning processes, the mechanism is prone to jamming in the harsh processing environment of juicy and debris-rich seafood.

[0005] In view of the above problems, there is an urgent need for an automatic shelling and cleaning machine for crustaceans to overcome the shortcomings that prevent existing technologies from solving the technical deficiencies of high efficiency, high quality, safety and low cost in the industrial processing of crustaceans. Summary of the Invention

[0006] In view of this, this application provides an automatic shelling and cleaning machine for crustaceans. The main purpose is to solve the technical problems existing in the prior art, such as "static rigid shelling leading to high shell breakage rate and high meat damage rate" and "single function of processing equipment and high cost of manual intervention".

[0007] The present invention provides an automatic shelling and cleaning machine for crustaceans, comprising a frame, and a clamping module, a cleaning module, and a cutting module disposed on the frame; further comprising a transmission module having a closed-loop conveying trajectory and a shelling module; multiple clamping modules are equidistantly fixedly assembled on the transmission module, and pass sequentially through the processing space of the cleaning module, the cutting module, and the shelling module along the conveying trajectory under the drive of the transmission module; the cutting module includes a main shaft and multiple cutting blades coaxially spaced and fixed on the outer periphery of the main shaft; The shell removal module includes a guide rail, a guide rail slider slidably mounted on the guide rail, a fourth motor fixedly mounted on the guide rail slider, and a blade of the shell removal device that is connected to the power output end of the fourth motor. The guide rail slider is constrained to have a single degree of freedom of sliding linearly along the guide rail, and the blade has a single degree of freedom of rotating relative to the guide rail slider.

[0008] Furthermore, the transmission module includes a drive shaft, a sprocket sleeved on the outer periphery of the drive shaft, and a chain link meshing with the sprocket for transmission. The clamping module is fixedly connected to the side wall of the chain link and moves synchronously with it.

[0009] Furthermore, the clamping module includes a clamping base plate, a first clamping upper plate mounted on the clamping base plate, a first clamping upper plate base plate positioned below the first clamping upper plate, and a first rotating shaft hinged between the clamping base plate and the first clamping upper plate base plate; the clamping base plate and the first clamping upper plate form a clamping space for accommodating crustacean seafood products; The first clamping upper plate and the bottom plate have a degree of freedom to rotate relative to the first rotating shaft.

[0010] Furthermore, the transmission module also includes a clamping plate with a variable diameter fixed inside the frame. The outer contour surface of the clamping plate with a variable diameter has a convex circular section with a gradually changing radius of curvature and a release section with a decreasing radius of curvature. When the clamping module moves with the chain link, the bottom surface of the first clamping upper plate and the outer contour surface of the clamping plate with a variable diameter always maintain a sliding contact. When the first clamping upper plate slides to the convex circular section, the first clamping upper plate is pushed and flips open relative to the clamping plate.

[0011] Furthermore, the transmission module also includes a side plate fixedly connected to the chain link, and the clamping base plate of the clamping module is fixedly connected to the side plate through a coaxial locking member with a common hole.

[0012] Furthermore, the transmission module also includes a driving gear and a driven gear that meshes with the driving gear, with the driven gear being rigidly connected to the transmission shaft on the same axis.

[0013] Furthermore, the cleaning module includes a second rotating shaft arranged parallel to the conveying trajectory, and a cylindrical brush coaxially fixed to the outer periphery of the second rotating shaft, with the outer edge of the brush penetrating into the spatial motion envelope of the clamping module.

[0014] Furthermore, the cleaning module also includes a first motor, a motor pulley coaxially mounted on the output end of the first motor, a brush shaft pulley coaxially mounted on the end of the second shaft, and a belt of the cleaning module tensioned and wound around the outside of the brush shaft pulley and the motor pulley.

[0015] Furthermore, the frame includes a first support and a baffle plate that is horizontally fixed to the top of the first support; The shell removal module also includes a guide rail bracket, which is statically fixed to the bottom surface of the upper baffle of the device, and the guide rail is fixed on the guide rail bracket.

[0016] Furthermore, the automatic peeling and cleaning machine also includes a cutting module, which includes a sixth bracket statically fixed to the frame, a third motor bracket, a third motor fixed to the third motor bracket, a second motor pulley coaxially fixed to the end of the main shaft, and a second belt that is connected to the power output end of the third motor; the main shaft is rotatably mounted on the sixth bracket through bearings, and the cutting blades are distributed in a linear array along the axial direction of the main shaft.

[0017] Beneficial Effects: This invention provides an automatic shelling and cleaning machine for crustaceans. This application breaks away from the technical limitations of traditional static top-blade scraping. The shelling module is equipped with a combination mechanism of guide rail slider and rotating blades. During operation, the blades can both rotate to cut the connecting tissues of the crab shell and move along the guide rail via the slider to buffer the impact force brought by the transport of the crustaceans. This achieves a dual-degree-of-freedom flexible peeling combining rotational cutting and translational buffering, significantly reducing the shell breakage rate and ensuring the integrity of the crab meat.

[0018] The clamping module of this invention utilizes the underside of the base plate to abut against a variable-diameter plate fixed in the transmission module. It passively expands when passing the variable-diameter convex section and automatically tightens and closes upon reaching the short-diameter section using an internal torsion spring. Its purely mechanical contouring mechanism avoids the problems of short circuits and jamming that pneumatic or electronic grippers are prone to in crab molten material or waterlogged environments, achieving high-frequency, reliable gripping and adapting to crustaceans of different sizes.

[0019] In addition, this application uses a closed-loop chain transmission system to seamlessly complete four core processes for crustaceans: clamping, brush roller cleaning, array cutting blade shell opening, and slider blade shell removal, replacing manual transfer and reducing operating costs.

[0020] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0028] Example 1: As Figures 1 to 9 As shown, the present invention provides an integrated automatic shelling and cleaning machine for crustaceans, the static assembly structure of which is as follows: the skeleton of the automatic shelling and cleaning machine is composed of a frame 1, including a first support 101 at the bottom and a device upper baffle 102 at the top, and all functional modules are rigidly attached to the frame 1 for positioning.

[0029] In one feasible embodiment, the automatic shelling and cleaning machine disclosed in this application includes a frame 1, a clamping module 2, a cleaning module 3, a transmission module 4 with a closed-loop conveying trajectory, a cutting module 5, and a shelling module 6 disposed on the frame 1. The transmission module 4 is the core conveying hub of the cleaning machine, and includes a drive shaft 402, a sprocket 403 sleeved on the outer periphery of the drive shaft 402, and chain links 404 meshing with the sprocket 403. The clamping module 2 is fixedly connected to the side wall of the chain link 404 and moves synchronously with it.

[0030] In this embodiment, the transmission module 4 also includes a side plate 408 fixedly connected to the chain link 404, a drive gear 410, a driven gear 409 meshing with the drive gear 410, a clamping plate 407 fixed inside the frame 1, and a second motor 413.

[0031] The second motor 413 is mounted on the first bracket 101 and connected to the driving gear 410 via the driving gear flange 411. The driving gear 410 meshes with the driven gear 409. The driven gear 409 is mounted on the drive shaft 402, and the two are rigidly connected coaxially. The two ends of the drive shaft 402 are supported by the fourth bracket 401, and sprockets 403 are sleeved on it. A chain plate 406 is installed on the inner side of the support plate 405, and a clamping plate with a variable diameter 407 is fixed inside the frame 1. The sprockets 403 drive the chain link 404 to move. The side plate 408 is connected to the chain link 404.

[0032] In one feasible implementation, multiple clamping modules 2 are provided, and the multiple clamping modules 2 are equidistantly fixedly assembled on the transmission module 4. Driven by the transmission module 4, they sequentially pass through the processing spaces of the cleaning module 3, the cutting module 5, and the shelling module 6 along the conveying trajectory. The clamping modules 2 are used to fix crustacean seafood products. Specifically, the clamping module 2 includes a clamping base plate 201, a first clamping upper plate 202 assembled on the clamping base plate 201, a first clamping upper plate base plate 203 positioned below the first clamping upper plate 202, and a first rotating shaft 204 hinged between the clamping base plate 201 and the first clamping upper plate base plate 203; wherein, the clamping base plate 201 and the first clamping upper plate 202 form a clamping space for accommodating crustacean seafood products.

[0033] In this embodiment, the crustacean seafood product is taken as crab. The clamping base plate 201 is fixedly connected to the side plate 408 on the transmission chain with the same hole bolt. The first clamping upper plate base plate 203 has a degree of freedom of rotation relative to the first rotating shaft 204. Specifically, the first clamping upper plate base plate 203 is hinged to the clamping base plate 201 through the first rotating shaft 204, and the first clamping upper plate 202 is directly fixed to the upper side of the base plate 203.

[0034] In this embodiment, the outer contour surface of the clamping plate variable diameter plate 407 has a convex circular section with a gradually changing radius of curvature and a release section with a decreasing radius of curvature; when the clamping module 2 moves with the chain link 404, the bottom surface of the first clamping upper plate bottom plate 203 and the outer contour surface of the clamping plate variable diameter plate 407 always maintain a sliding contact fit; when the first clamping upper plate bottom plate 203 slides to the convex circular section, the first clamping upper plate bottom plate 203 is pushed and flips open relative to the clamping bottom plate 201.

[0035] In one feasible implementation, the cleaning module 3 includes a second rotating shaft 302 arranged parallel to the conveying trajectory, a cylindrical brush 303 coaxially fixed to the outer periphery of the second rotating shaft 302, a first motor 308, a motor pulley 305 coaxially mounted on the output end of the first motor 308, a rotating shaft pulley 304 coaxially mounted on the end of the second rotating shaft 302, and a belt 306 tensioned around the outer side of the rotating shaft pulley 304 and the motor pulley 305 of the cleaning module. Specifically, in the cleaning module 3, the second bracket 301 is fixed on the clamping plate variable diameter plate 407 and supports the second rotating shaft 302. The brush 303 is disposed on the second rotating shaft 302, and its outer edge penetrates into the spatial motion envelope of the clamping module 2. The first motor 308 drives the brush 303 to rotate through the belt 306, the motor pulley 305, and the rotating shaft pulley 304 of the brush.

[0036] In one feasible implementation, the cutting module 5 includes a sixth bracket 501, a third motor bracket 505, a third motor 506 fixed to the third motor bracket 505, a second motor pulley 503 coaxially fixed to the end of the main shaft 502, and a second belt 504 drivingly connected to the power output end of the third motor 506. The main shaft 502 is rotatably mounted on the sixth bracket 501 via bearings, and the cutting blades 507 are linearly arrayed along the axial direction of the main shaft 502. Specifically, in this application, the sixth bracket 501 is statically fixed to the frame 1. The third motor 506 drives the second motor pulley 503 via the second belt 504, thereby driving the main shaft 502 to rotate. Three cutting blades 507 are equidistantly locked and fixed on the main shaft 502.

[0037] In one feasible implementation, in the shell removal module 6, the guide rail bracket 601 is suspended on the bottom surface of the device baffle 102, and the guide rail 602 is statically fixed on the guide rail bracket 601. The guide rail slider 603 is embedded in the guide rail. The fourth motor bracket 604 is mounted on the guide rail slider 603, and the fourth motor bracket 604 houses the fourth motor 605. The output shaft of the fourth motor 605 is connected to the seventh bracket 607 via the fourth motor flange 606, and the blades 608 of the shell removal device are evenly distributed around its end circumference.

[0038] In one feasible implementation, the dynamic working principle of the automatic peeling and cleaning machine of the present invention is as follows: First, after the equipment is powered on, the operator places the crustacean seafood into the clamping module 2 in the feeding area.

[0039] The second motor 413 starts, and through the reduction transmission of the driven gear 409 and the driving gear 410, it transmits power to the transmission shaft 402, driving the sprocket 403 to rotate. The chain link 404 carries the clamping module 2 to move along the closed-loop path. When the first clamping upper plate bottom plate 203 slides past the static clamping plate variable diameter plate 407, its abutting part is pressed by the convex round section (the longer side of the cam outer diameter) of the clamping plate variable diameter plate 407, overcoming the torque of the internal torsion spring and causing the clamping module 2 to open, at which point it is in the preparation state; as the chain continues to move forward, when the abutting part slides down to the release section of the clamping plate variable diameter plate 407, that is, the shorter side of the cam outer diameter, the clamping module 2 automatically clamps the crustacean seafood tightly under the action of the release of the elastic potential energy of the internal torsion spring.

[0040] In this application, regarding the cleaning of crustacean seafood: when the crustacean seafood is held and passes through the cleaning module 3, the first motor 308 rotates at high speed, and the belt drive causes the brush 303 to perform high-speed flushing and cleaning of the crustacean seafood's belly and back.

[0041] The crustacean continues to the cutting module 5. The motor of the drive gear, namely the third motor 506, drives the main shaft 502 to rotate at high speed via a belt. The three cutting blades 507 precisely cut the joint between the ventral and carapace of the crustacean, destroying the integrity of the crab shell structure.

[0042] When the cut crustacean reaches below the shelling module 6, the fourth motor 605 drives the blade 608 of the shelling device to rotate in a spiral motion. At the moment the blade 608 contacts the crab shell, the crab shell, along with the chain, has a forward horizontal momentum. This force pushes the guide slider 603 to passively slide along the guide rail 602 to avoid contact. During this sliding and force-relieving process, the high-speed rotating blade 608, like a "skillful push," completely separates the carapace from the crab meat, avoiding the fragmentation caused by hard squeezing.

[0043] Example 2: This embodiment is a further equivalent replacement for the core mechanical structure disclosed in Example 1 above: In this embodiment, the transmission method of the device is replaced as follows: In Example 1, the cleaning module 3 and the cutting module 5 use belt pulley transmission, such as the second belt 504. In seafood processing workshops with heavy oil stains and extreme slipperiness, in order to prevent belt slippage, the transmission method can be replaced by a "gear meshing transmission pair" or a "sprocket and chain transmission pair", which can also transmit the rotational torque of the motor to the actuator shaft, such as the main shaft 502 or the second rotating shaft 302.

[0044] The mechanism replacement of the shelling module 6 in this embodiment compared to Embodiment 1 is as follows: In Embodiment 1, the guide rail slider 603 adopts a passive sliding avoidance mechanism without power. To achieve active avoidance of large crustaceans with extremely high production volumes, the guide rail slider can be replaced by an active linear motion module driven by a "pneumatic rodless cylinder" or a "linear motor". When the visual sensor or manual detection indicates the arrival of the crustacean, the guide rail slider 603 is actively controlled to move backward synchronously at a specific speed, so that the relative cutting speed between the shelling blade 608 and the crab shell is maintained at an optimal constant value.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
